I just installed Python 3.10 on my laptop (Ubuntu 20.04).

Running a Jupyter Notebook inside of VS Code works with Python 3.9 but not with Python 3.10. I get the error message: Running cells with 'Python 3.10.0 64 bit' requires ipykernel installed or requires an update.

Things I tried:

• Clicking on reinstall, which runs:

/usr/bin/python3.10 /home/joris/.vscode/extensions/ms-python.python-2021.10.1365161279/pythonFiles/shell_exec.py /usr/bin/python3.10 -m pip install -U --force-reinstall ipykernel /tmp/tmp-12568krFMIDJVy4jp.log

• Running pip3 install --upgrade ipykernel jupyter notebook pyzmq (from this thread).

Edits

• As asked in the comments, here is the output when I click the "reinstall" button:

/usr/bin/python3.10 /home/joris/.vscode/extensions/ms-python.python-2021.10.1365161279/pythonFiles/shell_exec.py /usr/bin/python3.10 -m pip install -U --force-reinstall ipykernel /tmp/tmp-10997AnLZP3B079oV.log

CodePudding user response：

I don't think ipykernel is compatible with 3.10.

Below is the message I receive when I try to install ipykernel with the following command: conda install -c anaconda ipykernel

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - ipykernel -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.5,<3.6.0a0|>=3.9,<3.10.0a0']

Your python: python=3.10

Solution:

I recommend creating a virtual environment using conda or another library.

To get you started:

1. Install Anaconda.
2. Enter the following commands. [Note: These are the Windows commands - may vary slightly on Mac and Linux.]

# Create virtual environment
# Use a version of Python that is less than 3.10
conda create --name your_env_name python<3.10

# Activate new environment
conda activate your_env_name

# Install ipykernel
conda install -c anaconda ipykernel

# Add this new environment to your Jupyter Notebook kernel list
ipython kernel install --name your_env_name --user

# Windows only: When trying to launch `jupyter notebook`, you may receive a win32api error.
# The command below fixes that issue.
conda install -c anaconda pywin32
